Description

Technical Field

[0001] This application relates to the field of automated production and processing technology, and in particular to a dual-station tooling placement mechanism. Background Technology

[0002] During the assembly and machining of drive shafts, pins are typically inserted into the pin holes to facilitate the transmission of lateral forces or torques, enabling the drive shaft to effectively transfer power to other components and achieve efficient power transmission within the mechanical system. Because the drive shaft has a cylindrical structure, during placement, the drive shaft may roll at the positioning point, causing the pin holes to shift, thus affecting the assembly effect. While using a positioning fixture to clamp and fix the drive shaft can prevent pin hole shifting, the clamping end can easily interfere with the press's output end. Furthermore, excessive clamping force can easily cause scratches or pressure marks on the drive shaft surface, resulting in drive shaft defects. Summary of the Invention

[0003] This application provides a dual-station tooling placement mechanism to solve the problem in the prior art that during the pin assembly process of the drive shaft, it is not convenient to limit and fix the drive shaft, which easily leads to pin hole misalignment or damage to the drive shaft due to clamping.

[0004] This application provides a dual-station placement fixture mechanism, including a positioning fixture for placing a drive shaft. The positioning fixture includes a fixture base plate and a placement seat disposed on the fixture base plate. The placement seat is provided with two placement stations, which are U-shaped. The drive shaft is movably placed on the placement station.

[0005] Furthermore, the placement seat is provided with a positioning structure at the pin hole position of the drive shaft corresponding to the placement station. The positioning structure includes a return spring disposed inside the placement seat and a positioning pin connected to the return spring. The placement station of the placement seat is provided with a positioning through hole corresponding to the pin hole of the drive shaft. The positioning pin extends movably from the positioning through hole and is embedded in the pin hole of the drive shaft.

[0006] Furthermore, positioning cylinders are respectively provided on both sides of the placement seat, and positioning push rods are connected to the output ends of the positioning cylinders. A limiting platform is provided at the bottom of the positioning pin, and the front end of the positioning push rod is in active contact with the top or bottom surface of the limiting platform. The positioning cylinder drives the positioning push rod to be in active contact with or away from the limiting platform.

[0007] Furthermore, the front end of the positioning push rod is a conical surface, an arc surface, or an inclined surface, and the positioning push rod makes movable contact with the top or bottom surface of the limiting platform of the conical surface, arc surface, or inclined surface at the front end.

[0008] Furthermore, a first drive shaft detection sensor is provided on the placement station, and the first drive shaft detection sensor is embedded inside the placement seat.

[0009] Furthermore, a first drive shaft detection sensor is provided on the placement station, the first drive shaft detection sensor is embedded inside the placement seat, and a second drive shaft detection sensor is provided on the side of the placement seat corresponding to the extension position of the placement station. The first drive shaft detection sensor and the second drive shaft detection sensor are respectively located at corresponding positions close to both ends of the drive shaft.

[0010] Furthermore, this application also includes a servo slide, wherein the positioning fixture is disposed on the moving end of the servo slide, and the servo slide drives the positioning fixture to reciprocate.

[0011] Furthermore, a barcode scanning module is provided next to the servo slide, and a barcode label is affixed to the end of the drive shaft. The servo slide drives the positioning fixture to move to the side of the barcode scanning module, and the barcode scanning module scans and identifies the barcode label at the end of the drive shaft.

[0012] The technical solutions provided in this application have the following advantages compared with the prior art:

[0013] The solution provided in this application provides placement space for the drive shaft through a U-shaped placement station. Therefore, when the drive shaft is placed in the placement station, the two sides of the U-shaped structure of the placement station provide limiting for the drive shaft, thereby preventing rotation of the drive shaft at the placement station and affecting the positioning effect. This ensures that the pin holes on the drive shaft will not be misaligned during the pin assembly process. Simultaneously, the drive shaft does not require clamping or fixing via a clamping mechanism on its side, avoiding damage or scratches to the drive shaft surface caused by excessive clamping force, effectively ensuring the yield rate of the drive shaft.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0025] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0026] To address the problems in existing technologies where pin assembly of drive shafts is inconvenient for limiting and fixing the drive shaft, easily leading to pin hole misalignment or damage to the drive shaft due to clamping, this application provides a dual-station placement fixture mechanism. The solution provided in this application uses a U-shaped placement station to provide placement space for the drive shaft. Therefore, when the drive shaft is placed in the placement station, the two sides of the U-shaped structure of the placement station provide limiting for the drive shaft, thereby preventing rotation of the drive shaft in the placement station and affecting the positioning effect. This ensures that the pin holes on the drive shaft will not misalign during pin assembly. Simultaneously, clamping mechanisms are not required on the sides of the drive shaft for fixation, avoiding damage or scratches to the drive shaft surface caused by excessive clamping force, effectively ensuring the yield rate of the drive shaft.

[0027] Please see Figure 1 This application provides a dual-station placement fixture mechanism, including a positioning fixture for placing a drive shaft. The positioning fixture 1 includes a fixture base plate 11 and a placement seat 12 disposed on the fixture base plate 11. The placement seat 12 has two placement stations 121, each with a U-shaped structure. The drive shaft is movably placed on the placement station 121. The two placement stations 121 on the placement seat 12 limit the movement of the drive shaft by the U-shaped placement stations 121, thereby preventing the shaft from rolling and shifting, and providing good support for the drive shaft during pin assembly.

[0028] During operation, the U-shaped placement station 121 provides space for the drive shaft. When the drive shaft is placed in the placement station 121, the two sides of the U-shaped structure of the placement station 121 provide limiting for the drive shaft, preventing rotation of the drive shaft in the placement station 121 and affecting the positioning effect. This ensures that the pin holes on the drive shaft will not be misaligned during pin assembly. Simultaneously, the drive shaft does not require clamping or fixing via a clamping mechanism on its side, avoiding damage or scratches to the drive shaft surface caused by excessive clamping force, effectively ensuring a high yield rate for the drive shaft.

[0029] In some embodiments, please refer to Figure 2 , Figure 3 The placement seat 12 has a positioning structure 13 at the pin hole position of the drive shaft corresponding to the placement station 121. The positioning structure 13 includes a return spring 132 disposed inside the placement seat 12 and a positioning pin 131 connected to the return spring 132. The placement station 121 of the placement seat 12 has a positioning through hole 122 corresponding to the pin hole of the drive shaft. The positioning pin 131 extends movably from the positioning through hole 122 and is embedded in the pin hole of the drive shaft. When the drive shaft is placed on the placement station 121, the positioning pin 131 passes through the positioning through hole 122, thereby inserting the positioning pin 131 into the pin hole of the drive shaft to position and fix the drive shaft, preventing the drive shaft from being misaligned during the pin assembly process. When the press drives the pressure head push rod downward to push the pin into the pin hole of the drive shaft, it will push the positioning pin 131 downward and compress the return spring 132 at the same time, so that the positioning pin 131 retracts into the placement seat 12, thereby avoiding affecting the assembly of the pin.

[0030] In some embodiments, positioning cylinders 133 are respectively provided on both sides of the placement seat 12. The output end of the positioning cylinder 133 is connected to a positioning push rod 134. The front end of the positioning push rod 134 is a conical surface or an arc surface. A limiting platform is provided at the bottom of the positioning pin 131. The front end of the positioning push rod 134 is in active contact with the top or bottom surface of the limiting platform. The positioning cylinder 133 drives the positioning push rod 134 to be in active contact with or away from the limiting platform.

[0031] Before the drive shaft is placed on the placement station 121, the positioning cylinder 133 is in the extended state. At this time, the positioning push rod 134 extends and contacts the top surface of the limiting table, limiting the positioning pin 131 so that the positioning pin 131 remains retracted inside the placement seat 12. At the same time, the return spring 132 is compressed, so that the return spring 132 accumulates elastic potential energy.

[0032] After the drive shaft is placed on the placement station 121, the positioning cylinder 133 retracts, causing the positioning push rod 134 to move away from the positioning pin 131. When the front end of the positioning push rod 134 separates from the limiting platform of the positioning pin 131, the obstruction of the positioning push rod 134 on the limiting platform is removed, thereby releasing the return spring 132. The return spring 132 converts elastic potential energy into kinetic energy, thereby pushing the positioning pin 131, causing the positioning pin 131 to pass through the positioning through hole 122 and be inserted into the pin hole of the drive shaft placed on the placement station 121, thereby achieving fixed positioning of the drive shaft.

[0033] When the press drive head push rod moves downward to push the pin into the pin hole of the drive shaft, the pin pushes the positioning pin 131 back into the placement seat 12, compressing the return spring 132. Then, the positioning cylinder 133 is activated, pushing out the positioning push rod 134, causing the positioning push rod 134 to move above the limiting platform. In this way, the positioning pin 131 is fixed by the blocking action of the positioning push rod 134 on the limiting platform. By setting the front end of the positioning push rod 134 as a conical or arc-shaped surface, after the positioning pin 131 is pushed down by the pin, since the front end of the positioning pin 131 still extends out of the positioning through hole 122, when the positioning cylinder 133 drives the positioning push rod 134 to extend, the positioning push rod 134 contacts the top edge of the limiting platform through the conical or arc-shaped surface at its front end. As the positioning push rod 134 moves, it pushes the limiting platform down a certain distance through the conical or arc-shaped surface, thereby ensuring that the positioning pin 131 retracts into place and avoiding interference with the assembly or unloading process of the drive shaft and the pin.

[0034] In some embodiments, please refer to Figure 1 A first drive shaft detection sensor 14 is installed on the placement station 121, and the first drive shaft detection sensor 14 is embedded inside the placement base 12. The first drive shaft detection sensor 14 detects the drive shaft placed on the placement station 121. When the first drive shaft detection sensor 14 detects material in the detection area, it is determined that the drive shaft has been placed on the placement station 121. When the first drive shaft detection sensor 14 does not detect material in the detection area, it is determined that no drive shaft is placed in the current placement station 121. This satisfies the detection of the incoming material status during the automated processing, and then the subsequent assembly work is executed through the preset program in the control system.

[0035] In some embodiments, a first drive shaft detection sensor 14 is provided on the placement station 121, embedded inside the placement base 12. A second drive shaft detection sensor 15 is provided on the side of the placement base 12 corresponding to the extension position of the placement station 121. The first drive shaft detection sensor 14 and the second drive shaft detection sensor 15 are respectively located at corresponding positions near the two ends of the drive shaft. Since the drive shaft has a certain length, if only the first drive shaft detection sensor 14 is used to detect the drive shaft, there is a possibility of misjudgment. For example, if the drive shaft is placed on the placement station 121 but has not entered the detection range of the first drive shaft detection sensor 14, the first drive shaft detection sensor 14 will determine that the current state is a material shortage, which may easily lead to repeated feeding. In addition, detection by only the first drive shaft detection sensor 14 can only simply determine whether a drive shaft is placed on the placement station 121, but cannot determine whether the placement position of the drive shaft meets the set requirements. Therefore, by setting a second drive shaft sensor in the extension direction of the placement station 121, and positioning the first drive shaft detection sensor 14 and the second drive shaft detection sensor 15 at corresponding positions at both ends of the drive shaft, when the drive shaft is accurately placed on the placement station 121, both the first drive shaft detection sensor 14 and the second drive shaft detection sensor 15 can detect the arrival of the drive shaft, thus determining that the drive shaft has been properly placed. If one of the first drive shaft detection sensor 14 or the second drive shaft detection sensor 15 detects the drive shaft while the other does not, it is determined that the placement position of the drive shaft is abnormal, and an alarm is issued through the control system to remind the operator to handle the abnormal situation in a timely manner.

[0036] In some embodiments, please refer to Figure 4 This application also includes a servo slide 2, with the positioning fixture 1 mounted on the moving end of the servo slide 2. The servo slide 2 drives the positioning fixture 1 to reciprocate. By driving the positioning fixture 1 with the servo slide 2, the requirements for moving the drive shaft placed on the positioning fixture 1 to below the press 2 for pin assembly are met, and after assembly, the drive shaft is moved to the unloading station for unloading. In the embodiment provided in this application, the placement seat 12 employs two placement stations 121, which can simultaneously place two sets of drive shafts. The servo slide 2 drives the positioning fixture 1 to move the two sets of drive shafts sequentially to positions corresponding to the press head rod of the upper press for pin assembly, effectively improving overall processing efficiency.

[0037] In some embodiments, a barcode scanning module is provided beside the servo slide 2, and a barcode label is affixed to the end of the drive shaft. The servo slide 2 drives the positioning fixture 1 to move beside the barcode scanning module, and the barcode scanning module scans and identifies the barcode label at the end of the drive shaft. The barcode label is a QR code or a barcode; in an optional embodiment, a QR code label is used. Before the pin pressing assembly of the drive shaft, the drive shaft is moved to the position corresponding to the barcode scanning module under the drive of the servo slide 2. The barcode scanning module scans and identifies the QR code on the drive shaft, which facilitates the binding and writing of subsequent pin assembly information, pressure sensor readings, and other information with the current product information of the drive shaft, satisfying the traceability of various processes of the drive shaft during the back-end processing.

[0038] The solution provided in this application provides placement space for the drive shaft through a U-shaped placement station. Therefore, when the drive shaft is placed in the placement station, the two sides of the U-shaped structure of the placement station provide limiting for the drive shaft, thereby preventing rotation of the drive shaft at the placement station and affecting the positioning effect. This ensures that the pin holes on the drive shaft will not be misaligned during the pin assembly process. Simultaneously, the drive shaft does not require clamping or fixing via a clamping mechanism on its side, avoiding damage or scratches to the drive shaft surface caused by excessive clamping force, effectively ensuring the yield rate of the drive shaft.
